To all afkom- 'iz may Concern.

Be it-known that we, THOMAS R. Vrwi and Jams 51V. FAssn'i'r, citizens ofthe United .ltttes residing inthe ,city and county of Denver and Stateof Colorado, have' in\.f'ented certain new and useful Improvements inIortable Electric Fans; andwe do declare the following to be av full,clear. and exact description of the invention, such as will enableothers skilled in the art to which -it appertains to make and use thesame, reference being hadto the accompanying drawings, and to thecharacters of reference markedthereon, which form a part of thisspecification. j

Our invent-ionl relates to improvements in `wei-table electric fans. Ourimproved fan is ot such shape and size that it may readily be carriedinthe pocket, and when` in use may be employed with or without a standor supporting bracket. 1When mounted on a bracket support, it may betilted Ato direct the current of air Aissuing therefrom in desireddirection between the horizontal and vertical, and either above or below`the axis ol' the pivot upon which it is adapted to swing.

Our in provedl device consist-s Iof a fan, a motor and abatteryassembled inccoper-v ative relation and mounted within -asubstantially cylindrical casing, the whole structure being of such massthat it may be readily carried in the pocket of the user. ll'hen carriedin the pocket, it should be removed lfrom its bracket support if it isdesired to employ or utilize the bracket feahthel base of the supportingbracketl` being partly broken' awayf `ifr. 2 a section taken on the line2-2, Figs. 1 vand 5, the lmttery,` however, being for the most partshown in elevation. Fig. 3 is a rtop plan or end view of the devicelooking in the direction of arrow 8, Fig. 1. Fig. t is a section takenon the line 1f-4, Fig. 2 viewed in the direction of the arrow. Fig. 5 isa section taken on the line Fig. '2 looking upwardly or in t-hedirection of the arrow adjacent the nnnteral 5. Fig.v (i is a sectiontaken en the same ,line looking in tlie'opposite direction or vthedirection of the arrow adjacent the numeral 6 at the Iopposite end ofthe line.

The same reference characters indicate the same parts in all the views.

Let the-numeral 7 designate the body of a preferably substantiallycylindrical c as'- ing, .whose lower portion is reinforced as shown at 8and interiorly threaded as shown at 9 to'receive the exteriorlythreadedpart 10 of a detachable casing member 12, the latter having a shoulder13 against which the lower edge of the part S) of the casing member Tabuts, when the parts are assemcasing makes the latter entirely smoothon the inside and adapted to receive a battery 14 for supplying currentto a' motor 15 which is arranged adjacent the battery, an insulatingmember 1G being interposed between the battery. and the bod-y of themotor. To the lower side of an insulating member 16 are secured twoconture. The bracket may be so small that it tacts 17 and 1S, theextremities of these connay be easily carried in the pocket when .tactsbeing attached to the insulating memtlie fan struct-ure is detachedtherefrom` or ber suitable fastening devices 19 and 20. yeven when thetwo parts are assembled if `hese contacts are insulated from eachotherit should be desired to do so.

As illustrated in the drawing, the casing is composed of three parts,namely` the central or body part, the lower part Awhich is readilyremovable from the bodypart, and the .upper detach. ble member or thecap, the upper .and `lower membersv .being preferably threaded upon thebody' or intermediate portion of the casing.

Having brieiy outlined our improved construction. we will-proceed todescribe the same. in ,det-ail.,,reference lbeing .made to theaccompanying drawing.y in which is illusl trate'd an embodiment thereof.

In this drawing: Figure 1 is a side elevaand are so arranged that whenthe battery is in place its opposite poles Z1 and 22 are in engagement.with the contacts 17 and 18 respectively. The `upper extremity o f thebattery is provided with a groove 23 adapt edto receive lthe innerextremity of a screw pin 24 when yth Abattery is in the proper positionto maintain'the necessary polarity or its proper position with referenceto the contacts 17 and' 18 as hereinafter more fully explained.'

Mounted above the insulating member 16 and' within the body 7 of thecasing is the `motor15 whose armature shaft 25 is journaled at .itslower extremity in the insulating member 16 and at its upper extremitytion of our improved Aportable electric fan,

bled. This structure of the two parts of the surrounded by an insulatingmember 54 or shape and interposed between 'the 'ated in the drawing',the lower end or what may be for convenience termed 70 the lower end 55,of the casing is and may form support for the device if desired. Thedevice, however, may be advantageously supported upon tl e upright arm56 of a bracket 57 having a base 58.l By 75 employing this bracket thebottom of the device may be supported above the surface' 59 and mountedto swing orrotate on the upper extremity 60 of the bracket arm by meansof a set screwl which is threaded into the 30 body of the casing asshown at G2 and journaled inthe bracket arm, a reinforcing memer 63being interposed between the top or' the bracket arm and the body of thecasing. By virtue of this construction, the device 85 ymay be secured inany desired position. rlhat is to say, it may occupy a verticalposition' or any other positionbetween the horizontal and vertical, andso that its upper eX- trem'ity from which the currenty ofair gener- 90?ate'clby the fan issues, may occupy a position either above or below theaxis oi the screw pin which connects the device with the in aninsulating member 26, metal bushings 27 and 28 being employed. rllhearmature shaft is provided with an extension 29 to which the fan memberB-O is attached, the a last named member being located within the upperpart'o'lthecasing'inember 7 its upper or outer extremity being journaledin a recess 3l formed in the center of a cap 32 which/isprovided with aiiange .33 which is u interiorly threaded to coperate with eXteriorthreadsformcd on thecasing part 7 when.` the members of the casing areassembled in coperative relation.

rlhe fan blades 34 are so shaped and arlh ranged that a current'o" airwill be directed outwardly through openings 35 formed on the top orouter extremity of the cap 32, the air being drawn in through theperforations 36 formed in the casing member 7 between 2c the motor andthe fan. Hence, when the' device is regularly employed, it is desirablethat the fan member should be so rotated as to direct the current of airoutwardly at the upper extremity of the structure and for his reason itis necessary that the battery be Vso arranged with reference to the.contacts l .17 andl as to rotate the armature shaft in afuniiformdirection. vFor this reason, the guide pin 24 and the recess 23 formedin the' motor are employed.

The electrical circuitmay be described as .rfollovvs: The current mayvbe said to pass v'from the' pole 22 of the battery to and through thecontact 18 thence through a wire 37 to an enteriorlyV located contact38' adapted to receive an adjustable slide 39 @equipped with amanipulating button 40, the button being movable in a slot al formed inthe contact 38. From the slide 39, when the to circuit is closed, thecurrent passes to and through a coperating contact 42' which the xslide39 also engages. From this Contact d2 the current passes through aconductor 4-3 toa terminal 44 of the field coil 45. The cure5 rentpasses thence through thecoils ot thev iield and thence from theoppositef'terminal patito-a brush 47, which engages the commlutator i8of the motor. From the commutator, the current passes through a wire a9to io the coils 50 of the motor armature and thence from the last namedcoils from a conductor 51ste another section of the commuta-- tor, andthence through a gbrush 52,.a, con ductor 53 and the contact 17 totheopposite pole .21ct the battery. l't is `not believed necessary to gomore into detail in describingthe motorcircuit as there is nothing newper se about ythe motor or the winding of held and armature. coils.l toits,.il-' luetrated in the drawing, the commuta'tor brushes aremountedon the insulating .member located at the upper end of the motor.vl'n addition to the insulating parts lfd 213 arranged at the upper andlower oifvthe motor, the latter is also bracket arm. i y

Fromth'eforegoing description, the use 95 'and operation of our improvedportable. pocket electric fan will be readily understood.. n

When the three members, the battery, the motor andthe tan are properlyassembled within the casing, and the detachable parts or" the latterapplied,A the slidel 39Ashould be vso adjusted as to break the circuit,that is, it should be moved downwardly into the cone,- tact 38 until itsopposite extremity is dis- 105 connected from the contact 42. Thenwhen-Y ever it is desired to operate the fan, it is only necessary toadjust the slide 39 by means of the button d() to bring it intoengagement with the contact l2 as well as the 11o contactS. When it isdesired to change the positihn of the device upon the bracket 57, it .isonly necessary to loosen the set screw 6l, move 'the device to theproper position, and then tighten the set screw. V

Attentionis Ycalled to the fact that the er:- terior contacts 38 and i-2are insulated from thercasing which is also true of the conductors\37andY which pass through perfora- 'tions iii -th'ehody of the casing. ltshould 12o also be stated' that the electric current employcd foroperating the motor is thoroughly insulated from the casing so that thelatter` may be handled without danger of shock from the current.Attention is 'further called to apertures 3 formed in-thebody 7 oi" thecasing between the battery and the motor. These openings provide for thecooling of the motor during operation. ot the latter. 3@
